An erodible bed sheared by a fluid flow, gas or liquid, is generally unstable, and bed forms grow. This review discusses the following issues, in light of the recent literature: What are the …
Sand, rice, sugar, snow, cement... Although ubiquitous in our daily lives, granular media still challenge engineers and fascinate researchers. This book provides the state-of-the-art of the …
AG Kidanemariam, M Uhlmann - International Journal of Multiphase Flow, 2014 - Elsevier
A numerical method based upon the immersed boundary technique for the fluid–solid coupling and on a soft-sphere approach for solid–solid contact is used to perform direct …
We propose a two-phase model having a Newtonian rheology for the fluid phase and friction for the particle phase to describe bed-load transport in the laminar viscous regime. We have …
A Fourriere, P Claudin, B Andreotti - Journal of Fluid Mechanics, 2010 - cambridge.org
It is widely accepted that both ripples and dunes form in rivers by primary linear instability; the wavelength of the former scaling on the grain size and that of the latter being controlled …
The stability of a granular bed sheared by a liquid flow is investigated using an erosion- deposition model for the moving grains. Extending to arbitrary wave number a previous long …
One of the physically least understood characteristics of geophysical transport of sediments along sediment surfaces is the well-known experimental observation that the sediment …
The mobile layer of a granular bed composed of spherical particles is experimentally investigated in a laminar rectangular channel flow. Both particle and fluid velocity profiles …

We present reproducible experimental measurements for the onset of grain motion in laminar flow and find a constant critical Shields number for particle erosion, ie, θ c …
